Benzene and Naphthalene Degrading Bacterial Communities in an Oil Sands Tailings Pond
Oil sands process-affected water (OSPW), produced by surface-mining of oil sands in Canada, is alkaline and contains high concentrations of salts, metals, naphthenic acids, and polycyclic aromatic compounds (PAHs). Residual hydrocarbon biodegradation occurs naturally, but little is known about the hydrocarbon-degrading microbial communities present in OSPW. In this study, aerobic oxidation of b...
متن کاملDraft Genome Sequences of Campylobacterales (Epsilonproteobacteria) Obtained from Methanogenic Oil Sands Tailings Pond Metagenomes
Draft genome sequences of two Campylobacterales (Sulfurospirillum sp. strain SCADC and Sulfuricurvum sp. strain MLSB [Mildred Lake Settling Basin]) were obtained by taxonomic binning of metagenomes originating from an oil sands tailings pond. Both genomes contain soxABXYZ genes involved in sulfur oxidation, highlighting their potential roles in sulfur cycling in oil sands tailings ponds.
متن کاملSulfur Biogeochemistry of an Oil Sands Composite Tailings Deposit
Composite tailings (CT), an engineered, alkaline, saline mixture of oil sands tailings (FFT), processed sand and gypsum (CaSO4; 1 kg CaSO4 per m(3) FFT) are used as a dry reclamation strategy in the Alberta Oil Sands Region (AOSR). It is estimated that 9.6 × 10(8) m(3) of CT are either in, or awaiting emplacement in surface pits within the AOSR, highlighting their potential global importance in...
متن کاملMicrobial Nitrate Processing in Shallow Groundwater in a Riparian Forest
We measured denitrification, immobilization, and respiration in microcosms that simulated groundwater conditions in a riparian forest in Rhode Island. Measured rates were compared with rates of NOj" removal measured in a companion study using a groundwater monitoring well network and 10-mo injection of NOf and a bromide tracer to groundwater in the same riparian forest. Limiting factors for den...
متن کاملEffects of a constructed wetland and pond system upon shallow groundwater quality.
Constructed wetland (CW) and constructed pond (CP) are commonly utilized for removal of excess nutrients and certain pollutants from stormwater. This study characterized shallow groundwater quality for pre- and post-CW and CP system conditions using data from monitoring wells. Results showed that the average concentrations of groundwater phosphorus (P) decreased from pre-CW to post-CW but incre...
